A little-known Ukrainian singer Aza Thretens to Sue Carly Rae...

Description:Jepson:Aza tells TMZ, "I'm shocked and surprised that these people wanted to sample my lyrics on their song. They didn't ask me for permission, they just took it. That's why I filed this lawsuit. When I first heard it on the radio, I was driving and almost got into an accident. I couldn't believe what I was hearing."
